ELECTRIC-LAMP RECEPTAOLE.

To all whom it may concern:

Be it known that I, MELCHOR H. FREIXAS, a citizen of the United States, residing at Brooklyn in the county of Kings and State of New York, have invented new and useful Improvements in Electric-Lamp Receptacles, of which the following is a specification.

This invention relates to certain novel and useful improvements in receptacles for electric lamps, plugs, etc.

In carrying out the present invention, it is my purpose to provide a receptacle of the class described which will be formed of a number of sections so arranged and correlated that they may be readily assembled and dismantled, and wherein the current carrying strips of the receptacle will be equipped with prongs adapted to penetrate the current carrying conductors, thereby enabling the receptacle to be connected across the conductor without the use of screws and similar devices. r

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter set forth and falling r. ithin the scope of the claims.

- In the accompanying drawings Figure 1 is a view in side elevation of a receptacle constructed in accordance with present invention. 7

Fig. 2 is a top plan view of the baseplate and shell carried thereby.

Fig. 3 is a collective view showing the parts of the receptacle in operative position. Referring now to the drawings in detail, 1 designates a base plate, which in the pres ent instance is circular in outline, and formed on the base plate concentrically thereof and inwardly of the peripheral edge of such plate is an upstanding flange 2, cut out, at diametrically opposite points, as at 3. Also formed on the base plate 1 at the periphery thereof and outstanding therefrom are curved lugs t spaced apart equal distances around the base platev and arranged concentrically of'the inner flange 2. Seated upon the baseplate 1 within the flange 2 1s athreaded metal shell5, having the inner edge thereof formed with inturned plates 6 connected to the base plate by means of screws 7. Engaging the plates 6 and held thereto by means of the screws 7 is a curved strip 8 and integral with the strip 8 and projecting outwardly through one of the cut out portions 3 is a finger 9 having the outer Specification of Letters Patent.

end off-set from the strip and seated in a re cess 10 formed in the base plate contiguous to one of theslugs 4. Secured to the base plate 1 at the center of the latter is one end of a finger l1 and the other end of the finger 11 projects through the other out out portion 3 1n the flange 2 and is ofiset and seated in a recess 12formed in the base plate. The inner end of the finger 11 is formed to provide a contact 13. Surrounding the shell 5 is an annulus 14: having the edge adjacent to the base formed with outstanding lugs 15 diametrically opposed and designed to enter the spaces between the flange 2 and the diaymetrically opposite lugs 4, the lugs 15 engaging the lugs & that are at right angles to the lugs contiguous to the outer ends of the fingers 9 and 11. The lugs 15 act to hold the adjacent edge of the annulus spaced apart 7 Patented June 5, 1291?. Application filed September 30, 1916. Serial No. 123,099. r I

from the outer ends of the fingers 9 and 11,

and secured to the outer ends of said fingers and outstanding therefrom are prongs 16 projecting toward the adjacent edge of the annulus and adapted to penetrate the current carrying wires. Threaded onto the outer end of the shell 5 is a collar 17 having the inner edge adapted to engage a shoulder 18 formed on the inner surface of the annulus 14: between the end edges of such annulus. Formed on the collar 17 at the outer end thereof is a shoulder 19 adapted to engage the adjacent end of the annulus 1450 that the collar and annulus will be securelv held upon the base plate. The base plate, the annulus, and the collar are formed of porcelain or other suitable insulating material.

In practice, the collar and annulus are removed from the base and the current carrying wires pressed upon the prongs 16, the prongs penetrating the insulation on the wires and engaging the conducting portions of the wires so that the current may be delivered to the receptacle. The annulus and the collar are now applied to the base and the edge of the annulus adjacent to the base acts to hold the current carrying wires firmly upon the prongs. The lamp or plug may now be threaded into the shell and when the center contact engages the contact 13 the circuit will be completed and the lamp ener- 'zed. While I have herein shown and described the preferred form of my invention by way of illustration, I wish it to be understood that I do not limit or confine myself to the precise details of construction herein described and delineated, as modification and i the base plate at the variation may be made within the scope of the claims and without departing from the spirit of the invention. d,

1. A receptacle of the class described comprisinga base plate, ashell secured to the base plateat the center thereof, an annulus surrounding said shell, a collar threaded onto the outer end of the shell and acting to hold the annulus upon the base, lugs onv he base edgeof said annulus diametrically opposed and acting to hold the. base edge and the annulus spaced apart from the base, a contact finger having "one end connected to said shell and the other end disposed in cured to the base and having the inner end thereof arranged at the center of the shell and insulated therefrom, and the outer end disposed within the space between the lower edge of said annulus and the base at a point diametrically opposite the outer end of the first finger, and means on the outer endsof said fingers adapted to engage the current carrying wires.

2. A receptacle of the class. described comprising a base plate, a shell secured to center thereof, an annulus surrounding said shell, a collar threaded onto the outer end of the shell and acting to hold the annulus upon the base, lugs on the base edge of said annulus diametrically opposed and acting to hold the base edge and the annulus spaced apart from the base, a contact finger having'one end connected to said shell and the other end disposed in the space between said annulus and base, a second contact finger secured to the base and having the inner end thereof arranged at the center of the shell and insulated therefrom, and the outer end disposed within the space between thelower 1 edge of said annulus and the base at a point diametrically opposite the outer end the space between said an-' nulus and baseya second, contact finger seend of the of the first finger, and prongs on the outer ends ofsaid fingers respectively adapted to penetrate the current carrying wires.

3. A receptacle of the class described comprising a base plate, a flange rising from the b ase'plate inwardly of the periphery thereof and concentrically with respect thereto, said flange being cut away at diametrically opposite points, a shell seated upon the base within the flange, an annulus surrounding the shell, lugs formed on the annulusand arranged Within the cut away portion of said flange, and a collar threaded onto the outer end of the shell Iand serving to hold the annulus upon the ase.

4:. A receptacle of the class described comprising a base plate, a concentrically disposed flange rising therefrom inwardly of the peripheral edge of the base, a shell seated upon the base within said flange, an annulus surrounding said shell, said flange being cut away at diametrically opposite of the flange and the spaces between said lugs,

nulus upon the base. p

- 5. A receptacle of the class described comprising a base plate, a flange rising from the base plate inwardly of the periphery'thereof and concentrically with respect thereto, said flange being cut away at diametrically opposite points, spaced lugs risfrom said annulus and arranged in the said cut away portions and a collar threaded on the outer shell and acting tohold the aning from the base and defining grooves in the space therebetween and said flange, a-

shell seated upon the base within the flange, an annulus surrounding the shell and engaging the base, and means for holding said annulus in position.

In testimony whereof I ailix my signature.
